  The SAP error message AQ285, which states "The field is used in other definitions," typically occurs when you attempt to delete or modify a field that is currently being referenced in other objects or definitions within the SAP system. This can happen in various contexts, such as when working with data dictionary objects, table definitions, or other related structures.
  Cause:
  
  Field Dependency: The field you are trying to modify or delete is being used in other database objects, such as tables, views, or structures.
  Data Dictionary Objects: The field may be part of a data element or domain that is referenced in multiple places.
